Description

This was similar requested a few times but this is a different approach.

current situation:

Tvh supports only nvenc (for Nvida GPUs) for hw accelerated transcoding, QSV is supported but has no real world usability (you need to patch/recompile your kernel with outdated patches + sign in for SDK ...) and was widely dropped in favor of vaapi that is supported by every Intel and AMD CPUs that are not older then ~6+ years that include an gpu.

So basically every low end CPU like the popular J1900,N3150,J3455 that are even at commercial NAS systems (Synology...) would be able to handle easily 2-3 Streams at the same time, the latest generation could even transcode H265 in real time without an problem.

Vaapi is completely integrated at the latest ffmpeg, Linux distributions support it also widely (because you only need the GPU driver) and even Tvh ffmpeg is getting build with --enable-vaapi.

What is missing:
Vaapi is used via command line switches, you can't just build ffmpeg with support for it and it works. full howto

ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i "input file" -vf 'format=nv12,hwupload' -map 0:0 -map 0:1 -threads 8 -aspect 16:9 -y -f matroska -acodec copy -b:v 12500k -vcodec 264_vaapi "output file"

possible solutions:
- Tvh offers a way to specify the command line that is used for transcoding (user could tune it their self)
- Tvh adds a profile for vaapi (this could be problematic due the different systems with maybe different paths to dri render)
- redo the transcoding profiles or "merge" the codecs branch from here https://github.com/lekma/tvheadend/tree/codecs that is sadly not finished (but works) and was intended to pred to Tvh

Feature #3831: VAAPI Encoding via FFmpeg.Rejected

History

#1 Updated by Jaroslav Kysela 5 months ago

Unfortunately, it seems that lekma has no time to work on the transcoding code and I have no ETA to port his changes to latest tvh. There's no such thing like command-line if you like to use the ffmpeg library directly - you have to build/use all things which the command line ffmpeg tool does.

The problem with the current tvh code is missing: "-vf 'format=nv12,hwupload'" and the /dev/dri device passing.

#2 Updated by C vH 5 months ago

To be honest I have no real knowledge how ffmpeg gets called from Tvh, I thought Tvh calls ffmpeg with some command line - there it would be relatively easy to adjust the used command line to call ffmpeg. No idea if this works this way but at least would be some workaround till a proper solution is at the table.

Then what about Gstreamer

Hello, when implementing vaapi support, take in mind that is possible to use vaapi without X11 installed, there is no need to compile with libva_x11. libra_drm is usable and you can compile only with this library when using a headless server.

You could compile vaapi when QSV is not present in your system. Current configuration script only active vaapi when you select QSV and always try to compile with libva_x11

Is easy to change this behavior, changing configure script and Makefile.ffmpeg but when you run tvheadend it fails to open h264_vaapi codec. FFMPEG and a especial Plex version with HW transcode are running fine on my headless server, so permission and installation is OK.

I am not familiarized with ffmpeg lib use, so I can not help too much. As beta tester but there are many people as me. I look at lekmark implementation but differs so much respect to mainline, so I could not include changes from one version to other.

Lekmark version is working great on my server, but is relative old and sometimes crash. Quality is good and performance and power usage is great !!!! On a Celeron J1900 you could transcode a Full HD to a 360p, 240p, 120p with an extra use of 1w. Linux system + tvheadend streaming = 9w, Linux system + tvheadend vaapi transcode and streaming = 10w !!!! And cpu use is around 12~20%

Hope you develop a great vaapi support for tvheadend

Sorry my bad english.

Regards, Gustavo

#5 Updated by Christian Brauwers 3 months ago

This would be really nice.

I was playing around on a Synology DS916+ with the ffmpeg_vaapi Version.
Its working great with 3 Streams ... Have the ability of setup everything in TVH would be fantastic.

#6 Updated by Jaroslav Kysela 3 months ago

Just a little note: We have a workaround now in latest tvh - the 'MPEG-TS Spawn' profile. You can run an external program which converts MPEG-TS to wanted output (using ffmpeg with vaapi support for example).

#8 Updated by Jaroslav Kysela 3 months ago

It seems that your libva is really obsolete. The vaQuerySurfaceAttributes() was added in Version 1.2.0 released in 25.Jun.2013. https://github.com/01org/libva/blob/master/NEWS . If you don't enable qsv (--enable-qsv) in tvh's configure, this code is not used.

could you show a basic example how to use it ? As you could use transcoding for an FullHD stream even at an RPi2/3 with ffmpeg these days this is pretty interesting :)

Just create new streaming profile - select 'MPEG-TS Spawn' type and write the command line to the appropriate field. The spawned task will have MPEG-TS stream on stdin (ffmpeg - '-i pipe:0' - and tvh expects the output on stdout while is 'pipe:1' for ffmpeg). Note that the output can be anything - just specify the correct mime type for HTTP clients.

#12 Updated by Ricardo Rocha 3 months ago

Since i am not an expert not even close with ffmpeg i will wait that Jaroslav or maybe C vH put a real comand line with ffmpeg example.

Jaroslav i didnt understand "Note that the output can be anything - just specify the correct mime type for HTTP clients." Could you be more specific.

Thanks

#13 Updated by Jaroslav Kysela 3 months ago

There are a lot of examples for the MPEG-TS input: https://tvheadend.org/projects/tvheadend/wiki/Custom_MPEG-TS_Input . The only difference is that your should replace INPUTLINK to 'pipe:0' which means stdin (standard input of the unix task) where TVH sends the received stream. The mime should match with the used muxer, so if you keep contents as MPEG-TS, it should be "video/mp2t", for matroska "video/x-matroska" etc. Google will help.

Also, the command line does expect the command, so remove pipe:// from the examples in the provided link.

#14 Updated by Martin Walter 3 months ago

Very, very nice, Jaroslav! This allows HW transcoding on all Synology devices, which has been a frequently requested feature in that community. Is this for TVH 4.4 onwards or are you going to backport it into TVH 4.2.4 as well?

#15 Updated by Christian Eiden 3 months ago

So this means something like this:

ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i pipe:0 -vf 'format=nv12,hwupload' -sn -c:v h264_vaapi -tune zerolatency -f mpegts pipe:1

(not working yet as I'm not very firm with ffmpeg)

#16 Updated by Christian Eiden 3 months ago

So this means something like this:

ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i pipe:0 -vf 'format=nv12,hwupload' -sn -c:v h264_vaapi -tune zerolatency -f mpegts pipe:1

not working yet as I'm not very firm with ffmpeg ... what am I doing wrong? A CLI call on a recordings is working ...

sudo ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i 'Black Hawk Down.ts' -vf 'format=nv12,hwupload' -sn -c:v h264_vaapi -tune zerolatency -f mpegts 'test.ts'

#17 Updated by Jaroslav Kysela 3 months ago

I suggest to do tests with:

unset DISPLAY
cat {INPUT_TS_FILE} | {FFMPEG_CMD_LINE_FOR_TVH_SPAWN_PROFILE} > {OUTPUT_TS_FILE}

Change {} to your requirement.

#18 Updated by Christian Eiden 3 months ago

Ok, I've been playing with this for a while now and get the following results:

I created a profile "spawn" with the command

ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i pipe:0 -vf 'format=nv12,hwupload,scale_vaapi=w=1920:h=1080' -sn -c:v h264_vaapi -qp 20 -bf 2 -c:a aac -tune zerolatency -f matroska pipe:1

Testing this on the CLI works fine with the following command:

cat "/media/hdd/tv/Cool Runnings.ts" | DISPLAY="" ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i pipe:0 -vf 'format=nv12,hwupload,scale_vaapi=w=1920:h=1080' -sn -c:v h264_vaapi -qp 20 -bf 2 -c:a aac -tune zerolatency -f matroska pipe:1 > "/media/hdd/tv/test.mkv" 

Running it inside TVH gives me the following logs:

...
Aug 26 12:58:08 tv tvheadend[740]: spawn: [AVFilterGraph @ 0x5644e8f82d00] No such filter: 'format=nv12,hwupload,scale_vaapi=w=1920:h=1080'
Aug 26 12:58:08 tv tvheadend[740]: spawn: Error reinitializing filters!
...

Anything I'm missing?

#19 Updated by Jaroslav Kysela 3 months ago

Remove ' characters. The argument split / escaping is a bit different in tvh and in shell. TVH does not use '' or "" for argument contents. It does only space split and \ escaping.

Thinking more about this - you're not first who hits this issue, so tvh should be more friendly for this ;-)

Added to v4.3-361-gaa2f92720 .

#21 Updated by Christian Eiden 3 months ago

Works, thanks!

#22 Updated by Chris Peltier 3 months ago

So in v4.3-361-gaa2f92720 '' can be used for argument contents? I've been following this thread with interest and I'm a new user of TVH.
I've got my ffmpeg vaapi working and tested at the command line and v4.3-361-gaa2f92720 running however htsp clients won't connect to the profile.
Is it the case where ffmpeg and htsp are mutually exclusive?

#23 Updated by Jaroslav Kysela 3 months ago

For HTSP protocol only 'htsp' and 'transcode' profiles can be used.

4.3-361 arguments: 'this is one argument' or "this is one argument" or this\ is\ one\ argument
before (only):     this\ is\ one\ argument

#24 Updated by Jaroslav Kysela 3 months ago

  • Target version set to 4.4

Marking as resolved. I did some tests on Intel hardware with v4.3-413-g4598008b9 . There's merged lekma's code with my extensions. The last my extension is that you can select the DRI device for decoding/encoding when you have multiple ones (like me with NVidia Optimus technology - missing fw for noveau so only Intel DRI was tested).

Please, create a new bug report for a specific issue.

#25 Updated by Jaroslav Kysela 3 months ago

thank you for integration, will publish some test builds (LibreELEC) and try to discover problems !

I have the same issue on Stretch, Jaroslav already knows. He told me to install kernel headers. I've tried that - no luck - so I'm rebuilding my kernel to make sure it's there - will report back.

01.org drivers is impossible to be uninstalled if GUI installed. #4548

#30 Updated by Jaroslav Kysela 3 months ago

I'm on fedora and the drm/drm.h is directly in kernel-headers package, but the same file is copied in libdrm-devel (as libdrm/drm.h). I added a check to configure in v4.3-414-g994de3d9f, so you can give a try.

#31 Updated by Alfred Zastrow 3 months ago

I've changed the #include statement to libdrm/drm.h and it comiles fine. But at the time being I don't get a picture back from a recording:

#32 Updated by Fer De Montanaro 3 months ago

I have a problem with vaapi and AMD GPU.

With mesa/libav with AMD hardware, is necessary to declare two environment variables:

Extra notes for AMD hardware supporting VCE:

If you have a supported GCN+ AMD GPU running on Linux with the mesa driver stack, you may be able to use the AMD VCE Block via VAAPI with an example such as the one shown below:

DRI_PRIME=1 LIBVA_DRIVER_NAME=radeonsi ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi \
-framerate 30 -video_size 1920x1200 -f x11grab -i :0.0 -f pulse -ac 2 -i 1 \
-vf 'format=nv12,hwupload' -threads 8 \
-vcodec h264_vaapi -bf 0 -acodec pcm_s16le output.mkv

I declare in /etc/profiles the variables, but tvheadend send and error because not found the encoder device, if i declare the variables in the command box in tvheadend other error appear:

tvheadend[828]: pass: Unable to start pipe 'DRI_PRIME=1 LIBVA_DRIVER_NAME=radeonsi ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -i pipe:0 -vf 'format=nv12,hwupload' -sn -c:v h264_vaapi -qp 20 -bf 2 -c:a aac -tune zerolatency -f mpegts pipe:1' (wrong executable?)

How set the variables to tvheadend find the encoder?

Thanks

#33 Updated by Jaroslav Kysela 3 months ago

@Alfred : Unset the 'deinterlace' flag in the codec settings (the hardware decoder deinterlaces the input anyway and it's settings for the software deinterlacer). I'll look into this later. And, again, report bugs separately.

#34 Updated by Jaroslav Kysela 3 months ago

@Fer De Montanaro: You're probably trying 'MPEG-TS Spawn' profile. You cannot define the environment variables in this way. I may add new field later, but for tests, use a script. Also, you can use the direct vaapi support in the recent tvh code (where you can select the rendering device).

Thanks for the response.

Where select the rendering device? I not found the option.

Yesterday i build tvh: 4.3-414~g994de3d9f (and yes, all dependencies satisfied, includes vaapi and drm.h) drm.h is not included in kernel headers in Debian, installing libdrm-dev from repo install this.

first i have been playing a lot with ffmpeg so probably i could have done something wrong...

i tried to use a ffmpeg from source so i can be able to use the vp9_vaapi with spawn profile...

but just when i was about to start my tests with spawn i am getting this:

is this version installed with tvheadend? because i saw it's missing vaapi so that option will never work on command line.

is it possible use spawn profile with own compiled ffmpeg and not that one "/usr/bin/ffmpeg-10bit"?

thanks

#43 Updated by Jaroslav Kysela 3 months ago

I don't understand your question. You can run any command to process the stream. It seems that ffmpeg-10bit does not have vaapi support or you passed a wrong argument. Test your command on command-line as first, as noted in comment number 17.

#44 Updated by Ricardo Rocha 3 months ago

I guess i did that but i will confirm.

When tvheadend installs it also install own ffmpeg right? Is that one "/usr/bin/ffmpeg-10bit"?

If i have a custom ffmpeg binary is it possible to make spawn profile use it? I ask this because tvh always try to use that one on /usr/bin/.

Thanks

#45 Updated by Jaroslav Kysela 3 months ago

No, tvh uses own compiled static ffmpeg library, but it does not create any ffmpeg executable. This binary is probably from https://www.johnvansickle.com/ffmpeg/ as printed to log.

#46 Updated by C vH 3 months ago

ffmpeg from https://www.johnvansickle.com/ffmpeg is known to have no vaapi/nvenc capabilities (as they won't work static linked)

You said HTSP clients? So I can use an HDHomeRun through the IPTV setup and use a VAAPI transcoding profile for mobile clients correct?

I plan to install the 4.2.3 package for the Synology 916+ NAS. Also, where do I get the proper FFMPEG to install?

#48 Updated by Brandon Shermer about 1 month ago

Also noticed that this is implemented in 4.4 versions. Either way would this eventually work for the HDHomeRun using the IPTV transcoding to a mobile phone using the TVHClient?

First remove libva1 and i965 packages

Remove intel-graphics-update-tool
https://01.org/linuxgraphics/forum/graphics-update-tool-discussions/how-remove-drivers-installed-intel-graphics-update-tool

a)
dpkg-query -f '${binary:Package}\n' -W | \
while read pkg; do apt-cache madison $pkg | head -n 1; done | \
grep -F 01.org | tee updated-packages.txt

b) remove the 01.org repository from your configuration:
sudo rm -i /etc/apt/sources.list.d/intellinuxgraphics.list
sudo apt-get update

remove the lines with i915-4.6.3-4.4.0-dkms and intel-graphics-update-tool from updated-packages.txt

c)
apt-get install --reinstall $(while read pkg x; do echo $pkg/xenial; done < updated-packages.txt)

Remove libva1 and i965 packages
Check with apt list –installed
Apt-get remove libva1 i965-va-driver
